Melexis introduces the MLX90514, a dual-input inductive sensor IC that simultaneously processes signals from two sets of coils to compute differential or vernier angles on-chip. The inductive sensor targets automotive applications, such as steering torque feedback, steering angle sensing, and steering rack motor control.

Traditionally, designers have combined two single-channel ICs or used magnetic sensors for many applications, Melexis said. However, with the move to electrification, autonomy, and advanced driver-assistance systems (ADAS), vehicle control systems have become more complex particularly in systems such as steering torque feedback, steering rack motor control, including steer-by-wire implementations, which need dual-channel position sensing to deliver accurate torque and angle measurements.

By integrating differential and vernier angle calculations on-chip, the MLX90514 reduces processing demands on the host system, enabling smaller and more streamlined sensor designs. By computing complex position information (such as differential or vernier angles) directly at the sensor it eliminates the need for multiple ICs, which reduces design complexity and component count.

The MLX90514 is Melexis’ first dual inductive application-specific standard product (ASSP). It offers several interface options—including SENT, SPC, and PWM for a standalone module, and SPI for embedded modules—with integrated on-chip processing. The SENT/SPC output accommodates up to a 24-bit payload, enabling high-fidelity transmission of two synchronized 12-bit channels, which is required for high-accuracy torque and angle sensing.

Key features include zero-latency synchronized dual-channel operation, external pulse-width-modulation (PWM) signal integration that allows reading PWM signals from external sources, and the capability to handle small inductive signals, which supports compact coil designs and tighter printed-circuit-board layouts for smaller sensing modules.

The MLX90514 enables ASIL-D-compliant sensing systems, as a Safety Element out of Context (SEooC), for automotive steering torque and angle applications. The inductive interface sensor is available now.

According to Thales, its MultiApp 5.2 Premium PQC is Europe’s first quantum-resistant smartcard to receive high-level security certification from ANSSI (the French National Cybersecurity Agency). Certified to the EAL6+ level under the Common Criteria framework, the smartcard also uses digital signature algorithms standardized by NIST in the U.S.

The MultiApp 5.2 Premium PQC leverages post-quantum cryptography to protect digital identity data in ID cards, health cards, and driving licenses. This new generation of cryptographic signatures is designed to withstand the vast computational power of quantum computers, both today and in the future.

“This first certification for a solution incorporating post-quantum cryptography reflects ANSSI’s commitment to supporting innovation, while upholding the highest cybersecurity standards,” said Franck Sadmi, Head of National Certification Center, French Cybersecurity Agency (ANSSI). “The joint work of Thales, CEA-Leti IT Security Evaluation Facility, and ANSSI is a strong signal that Europe is ready to lead the way in post-quantum security, enabling organizations and governments to deploy solutions that anticipate future risks, rather than waiting for quantum computers to become mainstream.”

Joining Omnivision’s Nyxel NIR line, the OX05C1S global-shutter HDR image sensor targets in-cabin driver and occupant monitoring systems (DMS and OMS). The 5-Mpixel sensor, with 2.2-µm backside-illuminated pixels, captures clear images of the entire cabin, enhancing algorithm accuracy even under challenging high-brightness conditions.

The OX05C1S leverages Nyxel technology to achieve high quantum efficiency at the 940-nm NIR wavelength, improving DMS and OMS performance in low-light environments. On-chip RGB-IR separation reduces the need for a dedicated image signal processor and backend processing.

With package dimensions of 6.61×5.34 mm, the OX05C1S is 30% smaller than the previous-generation OX05B (7.94×6.34 mm), providing greater mechanical design flexibility for in-cabin camera integration. Lens compatibility with the OX05B enables reuse of existing optics, simplifying system upgrades and reducing overall design cost.

The OX05C1S sensor is offered in both color filter array (RGB-IR) and monochrome configurations. Samples are available now, with mass production scheduled for 2026.

One of the first jobs I had, when I first got out of college, was for a company that designed and manufactured monitors for large trucks, the kind used in mining operations. This company was a small entity with around 25 employees and a couple of engineers. The main product was a monitor that sat on the dash of these trucks and watched over things like oil pressure, coolant temperature, and level, hydraulic pressure, etc. Variations of this monitor had 4, 5, or 6 indicator lights that lit if the monitored point went out of spec. An alarm also sounded, and the truck was shut down by a relay connection.

Do you have a memorable experience solving an engineering problem at work or in your spare time? Tell us your Tale

Another engineer and I decided it was time to bring this analog monitor into the microprocessor era. The idea was to monitor the same functions, but only have one indicator light with an LCD showing the issue. Along with the alarming function, we could also add more information on the LCD, like temperatures and pressure readings. It wasn’t a very complex design. At that time, micros didn’t typically have watchdog circuits, so we added one of the few external watchdogs available at the time. Our concern was that some transient would throw the micro off course, and we wanted the watchdog to reset the monitor in that case. The 24-V input voltage and all sensor inputs had some level of transient suppression (but, after several decades, I have forgotten what the circuit consisted of).

We completed a design, and it worked very well on the bench. Next, we hit it with various transients that we could generate. Not having access to any transient test equipment, we had to invent some methods to test this. Worse, we had no specs or general information on what kind of transients these trucks can experience, but we ourselves were satisfied that it was ready for a beta test.

After testing, we sent the monitor to a local mining company to have it installed on a working truck. We also sent a harness system with leads long enough to get to the sensors located around the truck. The company called us after they got the monitor mounted on the dash and all the sensors wired to the harness, so a visit was scheduled to test the monitor on a running truck.

I need to stop at this point to describe the truck. It was a 175-ton dump truck. There are bigger trucks now, but it was very large for the time. Picture tires 10 feet high and a 1600 HP diesel/electric generator system powering electric motors turning each wheel. The driver’s cab was about 18 feet off the ground and was reached using an attached ladder. The driver and the two of us climbed this ladder to begin the test.

To add to the pressure, there were a dozen or so managers and workers on the ground watching the tests. The mining company managers gave the go-ahead to begin. The driver started the truck (quit a roar)—the monitor fired up, and the LCD began showing the status of the monitored points… great!

After a few seconds, the truck shut down… not great. We looked at each other—a few seconds later, the truck roared alive again—monitor working—a couple more seconds, the truck shuts down—a few seconds later, the truck restarts, etc., etc., etc.

After a half dozen of these cycles, we told the driver to shut the truck down. We couldn’t tie up the million-dollar truck any longer, so we could not do any more investigation. We packed up our equipment and left with our heads down.

Back at the shop, we talked through what went on. We concluded that the monitor’s micro was disrupted by an unknown transient. The watchdog then discovered the code running amok and tripped the shutdown relay. The watchdog then rebooted the micro, resetting the relay, which allowed the truck to restart itself.

One of the major design issues was that some sensors required tens of feet of wire and were unshielded single leads (most sensors used chassis ground). These single wires (or should I call them antennas) could have been close to various relays and electric actuators on the truck, or worse yet, near the cabling used for the generator-to-motor system. Also, the watchdog, which did discover the issue, did not fulfill its function—it allowed the truck to restart.

This is where “Tales from the Cube” articles tell us how they fixed the issue by adding a larger resistor, fixing a bad solder joint, or reworking a reversed diode. In this tale, there is no happy ending. The boss didn’t want to continue with the project, and I’m sure the customer was not impressed. The project was cancelled. So why did I write this up?

I thought it was a good example of what can happen on engineering projects—sometimes they fail (moving from the lab to the field often exposes design issues), and sometimes you don’t get a chance to fix the design. Young engineers should understand this and not be disenchanted when it does. Don’t let it get you down. Remember, we learn a lot by failure.

Shortly after this project, we got the opportunity to design a full, micro-based dashboard for a large articulated truck. One of the things we designed was a fiber-optic cable data-transfer system to the back portion of the truck. This minimized the length of sensor wires, providing antennas for the transient. In this design, the system worked flawlessly.

The IEEE International Electron Devices Meeting (IEDM) is considered the premier forum where scientists and engineers come together to disclose, discuss, and debate the best recent R&D work in electron devices, semiconductors, and microelectronic technologies. The 71st annual IEEE IEDM conference will be held December 6-10, 2025, at the Hilton San Francisco Union.

Supporting the theme “100 Years of FETs: Shaping the Future of Device Innovations,” the 2025 IEDM technical program will consist of 295 presentations, plus a host of events.

“This year’s IEDM offers a preview of the next computing paradigm. We are witnessing the convergence of atomic-scale fabrication, 3D integration, and neuromorphic design, moving us beyond yesterday’s technology and even classical computing. From monolithic CFETs that redefine transistor density to in-memory computing that can mitigate the von Neumann bottleneck, more intelligent and more efficient technology is being built here,” said Gaudenzio Meneghesso, IEDM 2025 Publicity Chair, and Head of the Department of Information Engineering at the University of Padova.

“As AI is demanding unprecedented efficiency, the device community is rising to the challenge. IEDM 2025 showcases technologies that can power the next AI decade: from GaN chiplets for power delivery and silicon photonics for data transfer to 3D DRAM and FeFETs for in-memory computing. These device technologies will make the algorithms of tomorrow possible.”

“The pursuit of Moore’s Law has evolved from a simple race to shrink transistors into engineering in multiple dimensions. IEDM 2025 showcases this new era: we are scaling up with 3D stacking like CFETs and 3D DRAM, scaling laterally with atomic-layer-deposited channel materials, and scaling past CPUs with novel architectures like in-memory computing,” said John Paul Strachan, IEDM 2025 Publicity Co-Chair, Director of Peter Grünberg Institute, Forschungszentrum Jülich, and Professor at RWTH Aachen University. “This is the culmination of a century of FET innovation, pushing the boundaries of what is physically possible to compute.”
